These magazines and books are, of course, complementary. Partly, because they didn´t appear at the same time, partly, because they do not all deal with exactly the same subject. Furthermore, it has to be said that some publications give more reliable information than others. Therefore [L1 - L3] and [A] may be called “critical” editions, i.e. the remarks and dates of earlier printed books have been chequed and, if necessary, been corrected. So [A] cheques [JPGR], [ATN], [TBA] and [BU] (until 1980) - and many more, of course. The information of [F] depends on [ATN], [TBA] and [EOB]. The latter three titles, concerning recording and release dates, often differ from [BOR], [LWR] and [WCH].




Research methods:


As I didn´t have the opportunity to get first hand information, I always tried to find out the most reliable dates if I had the choice of several (different) ones. In most cases, the used data source is given in [  ]. The alternative dates which I did not use, are given as: [# xy]. The following list shows which publications I preferred for a certain subject:



Beatles studio sessions: [Lxx], [JPGR], [A], [ATN], [TBA], [EOB], [LWR], [WCH]

Beatles radio/TV activities: [Lxx]

Beatles releases Germany: [DB]

Beatles releases UK: [LWR], [WCH], [ATN], [A]

Beatles releases USA: [BOR], [LWR], [ATN]

Bootlegs: [Y], [D], [IB], [NFS], [URG.3], [BA], [BBN]

Get Back Sessions: Doug Sulpy, 910´s Guide, [BA]

Beatles Solo Activities 1970-2001: [BA], [BD2], [Bf], [BM]



In most instances, I tried to use the “best”, i.e. most reliable version. In some instances, however, I gave more than one version and left the question open for further discussion.
